Are the beliefs that "humanity must try to understand the universe" and "humanity has value" and "my life has a purpose" scientific or religious beliefs, in your view?
Because I think even scientists sometimes need to believe that their lives have a purpose. Especially when contemplating the infinite vastness of space.
You say we cannot believe something 'because we want to'. But do we not choose to believe that we matter?
"Humanity must try to understand the universe" is not a belief in the sense in which some people believe, for example, that God became man and died for man's sins. In fact, I don't know anyone who believes that "humanity must try to understand the universe." Trying to understand how nature works has an obvious evolutionary survival value, in that people who don't understand how really basic things function, such has how pray-animals migrate and which plants are poisonous and so on, don't live long enough to pass on their genes. Trying to understand the world we live in is just something we
do, like breathing, it's not about believing. Believing that God became man and died for mankind's sins has no evolutionary value; there is no natural selection pressure to believe this and pass on one's genes by virtue of having believed just this (rather than some other, possibly erroneous, belief). Whereas, if you erroneously believe hemlock to be not poisonous, it has an obvious survival dis-advantage.
Similarly, it is weird to talk of
believing that "humanity has value" and "my life has a purpose." Your life has a purpose or it doesn't -- your
believing it has a purpose or no purpose adds nothing to its having or not having a purpose. Your purpose, if you have one, is not to believe something. It's rather like breathing: my
believing I'm breathing adds nothing to my breathing.
